Place brie on a square of foil. Place cherries on top and sprinkle with brown sugar, vinegar and salt.
Close up the foil to create a packet to place on the grill.
Place packet on grill and cook 5 to 7 minutes. Brush bread with olive oil and place on grill. Watch carefully and turn when they start to brown. Remove to a plate.
Remove packet from grill and carefully open up the foil. Use a spatula to move brie to a platter. Place bread around and serve.
Notes
Substitute balsamic vinegar in place of cherry balsamic vinegar. Also, substitute your favorite bread.
